Recent events related to the lack of water in Brazil demonstrated that the reuse of water is an issue that needs to be explored. In the present study, research was conducted to determine a source of domestic water that can be treated and reused with simple equipment, produced by national industry, or available in the domestic market. It was selected the treatment of the bathwater from the shower. The results of the parameters analyzed, pH, conductivity, color, turbidity, COD, phosphorus, total suspended solids, oil and grease, bacteria, total nitrogen, ammonia nitrogen, and total coliforms indicates that the model used needs adjustments, odor removal, and optimization of the effluent residence time in the treatment tank. Corrected these inconsistencies the system could be converted into a product for domestic use in regions where there is a shortage of water.

Uv Dose

Control of gaseous emissions from livestock operations is needed to ensure compliance with environmental regulations and sustainability of the industry. The focus of this research was to mitigate livestock odor emissions with UV light. Effects of the UV dose, wavelength, TiO2 catalyst, air temperature, and relative humidity were tested at lab scale on a synthetic mixture of nine odorous volatile organic compounds (VOCs) and real poultry manure offgas. Results show that it was feasible to control odorous VOCs with both photolysis and photocatalysis (synthetic VOCs mixture) and with photocatalysis (manure offgas). The treatment effectiveness R (defined as % conversion), was proportional to the light intensity for synthetic VOCs mixtures and followed an order of UV185+254 + TiO2 > UV254 + TiO2 > UV185+254; no catalyst > UV254; no catalyst. VOC conversion R > 80% was achieved when light energy was >~60 J L−1. The use of deep UV (UV185+254) improved the R, particularly when photolysis was the primary treatment. Odor removal up to ~80% was also observed for a synthetic VOCs mixture, and actual poultry manure offgas. Scale-up studies are warranted.
